摘要： A pneumatic tire is reinforced by a thin annular composite band embedded in the crown portion of the tire to enable the tire to resist compressive forces in the tire when in an uninflated condition. The band is formed of a plurality of wound layers of first and second resin coated fiber tows wherein the first tow is formed of fibers twisted at a greater angle than the fibers in the second tow. Layers of the first tow are located adjacent the neutral axis of the band to provide interlaminar shear strength with the tow layers located adjacent the inner and outer surfaces of the band being formed predominately of the second tow to provide a high level circumferential stiffness. The intermediate tow layers are formed of both type of tows to provide a transition zone between the central interlaminar shear strength and the outer circumferential stiffness.

摘要： A run flat pneumatic tire has a thin annular band embedded in the crown portion of the tire. The band is formed of a composite material such as tows of fiberglass and/or graphite material impregnated with a resin. The resin coated tows are wound about a mandrel having at least one concave recess to provide the band with an anticlastic shape with an arcuate cross section and a concave surface facing radially outwardly.

摘要： A run flat pneumatic tire has a thin annular band embedded in the crown portion of the tire. The band is formed of a multilayer composite formed of wound layers of a material such as fiberglass and/or graphite impregnated with a resin. The band has a radial cross-sectional thickness with a neutral axis extending through the center in an axial direction. The radial thickness of the band decreases from an axial midpoint toward outer ends of the band to provide greater thickness in the center of the band to reduce interlaminar shear fatigue.

摘要： A laminate contains a composite, comprising a high melting point thermoplastic such as polyphenylene or epoxy and high modulus fibers such as carbon or graphite, which is encapsulated with a resin. A primer adheres the encapsulated composite to a rubber material such as a tire tread. Alternatively, an undertread layer adheres the tire tread to the primed encapsulated composite. The laminate can be used as a run flat belt in a tire.

摘要： A method for building a run flat pneumatic tire by precoating a thin high strength annular band of material with a layer of rubber to form a rubber/band composite. The rubber coated band composite is at least partially cured and then assembled between a body ply carcass and a tread package in a usual second stage tire building machine. The band can be encased completely with the rubber or the rubber can be applied only to the outside surface, the inside surface or the end edges of the band or any combination thereof.

摘要： A band element for mounting in the crown portion of a pneumatic tire to provide run flat ability to the tire in the event of loss of air pressure and to provide increased puncture resistance. The band is formed of flat strips of tape having fibers embedded in a resin matrix which are twisted and then pultrated to provide a rectangular cross sectional configuration. The twisted tape is wrapped about a mandrel and forms either the only layer, or the intermediate layer of a composite band in combination with inner and outer layers of flat tape or wound filament fibers, whereby the fibers in the tape extend across the central axis of the band to reduce interlaminar sheer. In another embodiment, a plurality of dimples or depressions are formed in the individual tape layers to extend a plurality of the fibers across the layer boundaries to reduce interlaminar sheer.

摘要： A run flat pneumatic tire is reinforced by a thin annular composite band imbedded in the crown portion of the tire in combination with a plurality of radial cords or plies in its sidewalls which have freedom in shear with respect to one another. The band is formed by a plurality of layers of material strips wherein each strip is wound in a helical pattern, with adjacent strips being wound at reverse angles to each other. Each layer is formed under sufficient pressure and at an elevated temperature whereby the band is prestressed in tension which decreases the maximum stress at the footprint area of the tire. The invention furthermore incorporates the method of imparting the prestress on the annular band during its manufacture.

摘要： A run flat pneumatic tire includes a thin annular band embedded in the crown portion of the tire wherein the band is formed with three distinct regions. Radially spaced inner and outer regions are formed of high modulus materials and a central region is formed of a material more elastic than the other two regions providing a band having high interlaminar shear strength. Reinforcing fibers are placed in various orientations in certain of the regions to enable various materials to achieve the required band stiffness for load carrying capability and the interlaminar shear strength at the central axis of the band.
